Time Reversal

At thirteen, Wei Ying creates an array he calls 'Time Reversal' which he uses to save Jiang Cheng from drowning. At fifteen, he dies in a tragic accident. Two years after that, Wen Ruohan has overcome the Nie-Lan-Jiang rebellion. The small clans as well as the great sects are almost completely obliterated. On the eve of her execution, Jiang Yanli hands Lan Wangji her shidi's childhood journal of tricks and talisman designs he invented. As she reminisces about Wei Ying, she sighs. "Wen Xu would have started torturing him long before the Nie and still be torturing him long after we're all dead. Either that or he would have found a way for us to all win. He would never accept an outcome where A'Cheng and I die like this."

What will the righteous Lan Wangji do when facing his own execution and holding a book containing an array that might allow him to change everything?
